This mounting is an integral part of the High-Frequency Prism System. When the speakers are mounted properly, the tweeter will be angled away from the listening position. That means that the surround channel speakers should be mounted with the tweeter angled towards the back wall of the

This speaker often produces more output than the left and right speakers combined. This speaker should be of the highest possible quality, and as similar as possible in response and radiation pattern to the left and right speakers. Three identical speakers are best, unless the center chan

If the surrounds must be located close to the listeners, aiming them at the room walls or even the ceiling can help to reduce any directional effect. As described above, this can produce a desirable result even in rooms where the surround speakers are an adequate distance from the listeners' heads. If the surrou

Even though your M&K Speakers have extremely high power handling ability (especially for Main speakers), they still can be damaged by relatively low powered amplifiers. While very few M&K Speakers are actually returned for service, the vast majority of those returned are not

Find the best location for the subwoofer for maximum output and flattest response (usually the corner closest to the listening position) 2.
